+    ### Tool summary:
     - `Paper search` looks for relevant papers given an arxiv id or a question.
     - `Arxiv embedding` shows the landscape of current galaxy evolution papers (astro-ph.GA)
     - `QA sources` brings it all together to give concise answers to questions with primary sources and relevant papers.
+
+    This is not meant to be a replacement to existing tools like the
+    [ADS](https://ui.adsabs.harvard.edu/),
+    [arxivsorter](https://www.arxivsorter.org/), but rather a supplement to find papers
+    that otherwise might be missed during a literature survey.
+    It is also only trained on astro-ph.GA (astrophysics of galaxies) papers currently,
+    if you are interested in extending it please reach out!
+
+    The image below shows a representation of all the astro-ph.GA papers that can be explored in more detail
+    using the `Arxiv embedding` page. The papers tend to cluster together by similarity, and result in an
+    atlas that shows well studied (forests) and currently uncharted areas (water).
